Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber test pens, in particular to an optical fiber jumper test pen. Background Art

[0002] In the field of fiber-optic communications and network maintenance, fiber optic patch cord test pens are an important testing tool, widely used for fiber optic link fault diagnosis, signal strength detection, and fiber optic location. Red laser pens, a common type of fiber optic patch cord test pen, operate by emitting red laser light from a built-in laser, leveraging the light-guiding properties of optical fibers to locate and detect the status of fiber optic links.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the existing red light pen design, the laser is usually set up as an integral part with the circuit board. Although this design simplifies the assembly process in structure, when the laser is damaged due to long-term use, environmental factors (such as temperature fluctuations, humidity changes) or improper operation, since the laser is tightly integrated with the circuit board, it is often necessary to replace the entire red light pen instead of replacing the laser alone. This "one damage, all damage" design mode not only increases the complexity and time cost of maintenance, but also significantly increases the economic cost of maintenance. Utility Model Content

[0004] In view of the fact that the above-mentioned existing lasers are usually integrated with the circuit board, although this design simplifies the assembly process in structure, it has the problem of having to replace the entire red light pen when the laser is damaged. Therefore, the present utility model is proposed.

[0005] Therefore, the purpose of the present invention is to provide a fiber optic patch cord test pen, the purpose of which is that: the test pen is divided into two modules, a laser and a circuit board, and the two modules are detachably connected. When damaged, only the corresponding damaged part needs to be replaced, thereby reducing maintenance costs.

A laser head is fixed at the center of the end of the laser emitter away from the conductive columns.

[0008] As a preferred solution of the fiber optic jumper test pen described in the utility model, a fixing ring is fixed inside the machine compartment and close to one end of the battery shell, and the battery circuit board is fixed to the top of the fixing ring by bolts.

[0009] As a preferred solution of the fiber optic jumper test pen described in the utility model, two limiting rings are fixed on the peripheral surface of the shell, a threaded connection sleeve is provided on the peripheral surface of the shell and located between the two limiting rings, and an external threaded sleeve is installed on the peripheral surface of the machine chamber and close to one end of the shell and threadedly connected to the threaded connection sleeve.

[0013] As a preferred solution of the fiber optic jumper test pen described in the utility model, the ceramic core is located inside the positioning sleeve, and the positioning sleeve is threadedly connected to the threaded fixing sleeve and presses the ceramic core between the ring and the threaded fixing sleeve.

[0014] Beneficial effects of the utility model:

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4, which is the first embodiment of the present utility model, provides a fiber optic patch cord test pen. This fiber optic patch cord test pen includes a battery shell 1 with a battery disposed therein. An end cap 11 is threadedly mounted on the rear end of the battery shell 1. A machine compartment 12 is integrally formed at the head end of the battery shell 1. A battery circuit board 15 is fixed inside the machine compartment 12. A PCB board 16 is fixed on the top of the battery circuit board 15. Two conductive tubes 17 are fixed on the top of the PCB board 16. The conductive tubes 17 are connected to the terminal of the PCB board 16 by wiring. A switch 13 is installed on the peripheral surface of the machine compartment 12.

[0027] The laser end 2 is detachably installed at one end of the machine chamber 12 away from the battery shell 1. The laser end 2 includes a shell 21 that is detachably connected to the machine chamber 12 through a thread. A laser emitter 26 is fixed to the center of the shell 21. Two conductive posts 261 are fixed to one end face of the laser emitter 26 close to the conductive tube 17, and the conductive posts 261 are in contact with the conductive tube 17 for conductivity. When the conductive posts 261 enter the interior of the conductive tube 17, they also align the shell 21 with the machine chamber 12. At this time, the shell 21 and the machine chamber 12 cannot move relative to each other, which makes it easier to fix the machine chamber 12 and the shell 21 together. A laser head 263 is fixed at the center of the circle of the end of the laser emitter 26 away from the conductive post 261. A connector 268 is detachably installed at the center of the end of the shell 21 away from the laser emitter 26, and a ceramic core 267 is installed between the laser head 263 and the connector 268.

[0028] The test pen is divided into two separate parts: a laser emitter 26 and a PCB board 16, and they are detachably connected. At the same time, when the two are fixed together, the laser emitter 26 and the PCB board 16 are automatically connected and conductive. The modular setting allows only the corresponding damaged part to be replaced when a part is damaged, reducing subsequent maintenance costs and avoiding waste of resources.

[0029] A fixing ring 14 is fixed inside the compartment 12 and close to one end of the battery shell 1 , and a battery circuit board 15 is fixed to the top of the fixing ring 14 by bolts.

[0030] Two limiting rings 24 are fixed on the peripheral surface of the outer shell 21, and a threaded connection sleeve 25 is provided on the peripheral surface of the outer shell 21 and located between the two limiting rings 24. An external threaded sleeve 18 threadedly connected to the threaded connection sleeve 25 is installed on the peripheral surface of the nacelle 12 and close to one end of the outer shell 21. The setting of the two limiting rings 24 serves to limit the threaded connection sleeve 25 and prevent the threaded connection sleeve 25 from detaching from the outer shell 21.

[0031] During use, the connection process between the laser emitter 26 and the PCB board 16 is as follows: the conductive pillar 261 is inserted into the conductive cylinder 17 and snapped in place, which makes the housing 12 and the housing 21 coaxial.

[0032] The threaded connection sleeve 25 is screwed onto the external threaded sleeve 18 , and the nacelle 12 and the housing 21 are fixed together through the threads of the threaded connection sleeve 25 and the external threaded sleeve 18 . Conversely, the threaded connection sleeve 25 can be removed from the external threaded sleeve 18 to separate them.

[0033] Example 2

[0034] Reference Figure 1-4 , which is the second embodiment of the present utility model, is different from the first embodiment in that:

[0035] A sleeve 22 is fixed to the end of the outer shell 21 away from the battery shell 1, and a dust cover 23 is hingedly installed on the sleeve 22 to shield the head end of the laser emitter 26. When the test pen is not in use, the dust cover 23 blocks the joint 268, thereby preventing dust from entering the laser emitter 26.

[0036] A fixing plate 262 is fixed to one end of the laser emitter 26 away from the conductive pillar 261 , and a through hole for the laser head 263 to pass through is provided at the center of the fixing plate 262 . The fixing plate 262 is fixedly connected to the housing 21 .

[0037] A ring 264 is embedded in the center of the side of the outer shell 21 away from the laser emitter 26, and the laser head 263 passes through the inner hole of the ring 264. A coaxial positioning sleeve 265 is welded to the end of the ring 264 away from the fixed plate 262, and a coaxial threaded fixing sleeve 266 is welded to the end of the joint 268 close to the positioning sleeve 265, and the threaded fixing sleeve 266 is threadedly connected to the positioning sleeve 265.

[0038] The ceramic core 267 is located inside the positioning sleeve 265 , and the positioning sleeve 265 is threadedly connected to the threaded fixing sleeve 266 to press the ceramic core 267 between the ring 264 and the threaded fixing sleeve 266 .

[0039] The positioning sleeve 265 is provided to, on the one hand, be threadedly connected with the threaded fixing sleeve 266 to press the ceramic core 267, and on the other hand, it also has a positioning effect on the ceramic core 267, making it convenient and quick to place the ceramic core 267, and the threaded pressing installation also makes it easy to replace the ceramic core 267.

[0040] During use, the threaded fixing sleeve 266 is threadedly connected to the positioning sleeve 265. The threaded fixing sleeve 266 is removed from the positioning sleeve 265, and then the ceramic core 267 is taken out upwards. The new ceramic core 267 is placed inside the positioning sleeve 265 and is in a conflicting state with the ring 264. Then the threaded fixing sleeve 266 is re-fixed on the positioning sleeve 265, and the ceramic core 267 is clamped between the threaded fixing sleeve 266 and the ring 264 to complete the replacement of the ceramic core 267.

[0041] The remaining structures are the same as those of Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
